I am confident that the technology that helps anonymize or expire card data instead of letting it live on servers everywhere is on its way. We have so many ways to scan information ad hoc now with things like QR codes, why can't something like that work in payments?

I've seen survey data suggesting that customers are more willing to let banks take actions like their cards to protect them now. So I think the banks definitely have an opportunity to make customers participate in protecting themselves with all of the increased awareness on security.

Not to minimize the seriousness of these breaches, but this trend (consumer concerns) could create an excellent opportunity for banks to educate the public and potentially regain some trust and credibility -- not only with consumers but also with regulators, politicians, etc.But it will require transparency that perhaps doesn't come so readily around security issues. If banks could somehow communicate the steps taken to improve security, and also expand digital capabilities in ways that don't sacrifice experience/convenience for security -- and vice versa -- it will be a win-win.
